TOOL FOR MAKING HYPODERMIC INJECTIONS Filed Dec. 4, 19504 Patented Feb. 3, 1953 UNITED STATES PATENT OFFICE TOOL FOR MAKING HYPODERIWIC INJECTIONS Claims.

My invention relates to the art of minimizing the danger of infection by first applying an antiseptic to the subject when a hypodermic injection is made. Specifically, I have invented a dispenser for antiseptics, which dispenser is capable of being secured to the hypodermic syringe so that a manipulation of the syringe will place the antiseptic on the point of injection before and after the injection and by using the hypodermic syringe as the handle for the antiseptic dispenser.

Herebefore, when hypodermic injections have been made, it has been common to swab the area with an antiseptic before and after injection. This is usually done by another than the one making injections or by the injector laying the hypodermic syringe aside while the antiseptic is being applied with swab held in an entirely separate instrument. The need to lay aside the hypodermic syringe and useaseparate instrument such as forceps or the like to apply the antiseptic to the point of injection causes considerable lost time. I have solved this problem in the art by providing an antiseptic dispenser that is capable of being mounted directly on the hypodermic syring itself.

It is the principal object of my invention to provide a hypodemic syringe and antiseptic dispenser combined in one unit whereby the time factor in making injections is greatly reduced as compared to present day technique.

It is a further object of my invention to provide a tool for making anti-septic hypodermic injections that is durable in use and economical to manufacture.

These and other objects will be apparent to those skilled in the art.

My invention consists in the construction, arrangement, and combination of the various parts of the device, whereby the objects contemplated are attained as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Fig. 1 is a fragmentary side view of my tool for making antiseptic hypodermic injections to show the relationship between the various parts of the tool. Dotted lines illustrate a different adjusted position of the dispenser,

Fig. 2 is a front view of the dispenser portion of the tool and its mounting bracket,

Fig. 3 is a cross sectional fragmentary view of the dispenser portion of the tool to illustrate the construction of the swab antiseptic metering and spreading element secured to the antiseptic container, and

Fig. 4 is a reduced diagrammatic view of my unitary tool for making antiseptic hypodermic injections illustrating its use before and after the injection with the syringe portion of my tool.

Referring to the drawings, I have used the numeral Hi to designate the fragmentary portion of a hypodermic syringe portion of my tool shown in Fig. 1 and to which the bracket collar H is secured in any suitable manner as by means of the set screw 12. The dispenser supporting basket element designated I3 is secured to the bracket collar and it may be either rigidly or movably secured. I have shown it secured in an adjustable fashion, which is considered the preferred method, by means of the hinge ill at the rear end of the bracket collar and the supporting pair of arms I5 which are hingedly secured near the forward end of the "basket by entering appropriate drilled passageways in the ear [6 formed on the forward end of the basket. Each of the adjusting arms i5 is formed to provide a slot 11 by means of bending the arm elements back upon themselves or in any suitable manner and these slots are embraced at the outside by the arm clamping bolt and nut assembly designated 18. At the inside, the arms 15 are abutted by the ear [9 provided with an appropriate passageway through which the bolt of the bolt and nut assembly I8 passes. Thus the arms may be clamped in any desired position along the slot [1. The basket itself is provided with a clamping nut 20 which screws onto the threaded bolt member 2! to draw the ends i3 of the upper basket band arrangement together. For this purpose it is desirable to have the threaded bolt 2| rigidly secured to one of the upper basket "band ends so that only the nut 20 need be manipulated to release or clamp the basket around the dispensing unit designated 22. The dispensing unit may be any suitable open end container such as a glass bottle or the like and. should be providedwith an applicating or dispensing element on the forward end. This may take the form of any suitable applicator such as the one shown in my Fig. 3, the preferred form, which is a wick element 23'extending upwardly to a swab portion 24 and surrounded by a pervious covering 25, the whole assembly being secured to a screw cap 26 with a hole designated 21 concentrically arranged and the band 28 securing all the elements of the applicator to the screw cap. This completes the description of my antiseptic dispenser and I will now proceed to describe its operation.

When it is desired to administer a hypodermic injection, the needle is rotated away from the subject as shown in Fig. 4 so that the dispenser surface 25 is brought into contact with the point where the injection is going to be made on the body of an animal or the like represented by the curved line designated 29. A few brief strokes with the applicator causes the absorbent material 24 under the cover 25 to be squeezed together arid thus push on to the skin 29 of the subject antiseptic solution which has been brought up to the dispenser 24 by the wick 23. The wick arrangement 23 merely aids in metering the appropriate amount of antiseptic solution on to the point of injection as the dispenser is usually tipped at an angle to permit gravity to allow the antiseptic to flow or fall to the point of application as shown at FigJl. As soon-as the point of injection has been sterilized by means of the antiseptic, the hypoderm'ics'yringe portion ofthe tool may then be rotated slightly to present'the needle,- the needle may be inserted into the subject, and the injection'made. As the needle-is Withdrawn, however, it is advisable to rotate the-tool againan'd swab slightly in order to guarantee an antiseptic injection. When 'it'is desired to refill the antiseptic container portion of the tool, the top-26 may be unscrewed from the container and more antiseptic placed therein. When the tool is used by veterinarians inoculating herds of swine or the like, the dispensing and spreading pad may be used for substantiallyone Whole herd. When work is begun on the new herd, however, it may be professionally desirable, although not absolutelynecessary, to remove the used and unattractive looking swab of-prior applications and-put a new one in its place. This is easily done by simply unscrewing the cap-26 and replacing the used applicator with a fresh one. The adjustment provided for the dispenser by means of the arms- 15 and the bolt and nut assembly l8 makes it possible for'each user to arrange thedispenser in the manner that proves most convenient for him. Whenever it-is desired, for any reason, to remove the dispenser unit from the syringe, it may readily be accomplished-by loosening the set screw I2 and slipping the syringe out of the bracket collar l I.

From the foregoing description, it can be seen readily that I have provided a tool for making antiseptic hypodermic injections whichgreatly facilitates, makes safer and speeds up hypodermic injections by providing a suitable antiseptic dispenser unified with the hypodermic syringe.

Some changes may be made in the construction and arrangement of my antiseptic dispenser and method of making same without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents which maybe reasonably included within their scope.
